How to mix concrete antifreeze? Jiangsu concrete antifreeze manufacturer, which is the best early strength antifreeze in North Jiangsu?

1. For construction at 0~ -5℃, 4~6% can be added.

2. When constructing at -5~-10℃, 5~8% can be added.

3. When constructing at -10~-15℃, 8~10% can be added.

Early-strength antifreeze uses special antifreeze materials, which can effectively reduce the freezing point of concrete and mortar, and greatly improve the antifreeze performance of concrete and mortar at negative temperatures. It can increase the early strength of concrete and mortar by more than 80% without reducing the later strength, thereby ensuring that the strength is equally developed under positive and negative temperature conditions. The effect is remarkable.

Antifreeze can be divided into strong electrolyte inorganic salts (chlorine salts, chlorine salt rust inhibitors, chlorine-free salts), water-soluble organic salts Compounds, compounds of organic compounds and inorganic salts, and compound antifreeze.
